All sterling silver and accented with two types of bali beads and lovley 5mm sterling silver twists... This bracelet can be ordered in a single double triple as shown and five strand bracelet. All sterling silver bracelet is designed using our all sterling silver beads in a 4mm and 5mm size and beautiful Swarovski Crystals (TM) in a 4mm size and bicone shape and our birthstone series. The entire bracelet is accented in sterling silver bali bead collections and sterling silver block letters. You may include personalization on each of the three strands. The bali beaded caps are a 4mm size along with the daisy spacers. The heart toggle clasp is also .925 sterling silver and makes the bracelet easy to take on and off yourself. We are using special connectors and joiners to keep the bracelet in alignment with all three strands; the connectors keep the multiple strand bracelet in a beautiful alignment so you can focus on each particular strand when wearing it and the strands to not overlap making it beautiful and easy to wear without tangling. You can order this bracelet in a single double triple four and five strand bracelet.
